In 2002, the Swedish government presented its Energy Policy Bill ?Co-operation for a Secure, Efficient and Environmentally-Friendly Energy Supply? (2001/02:143). This report, approved by Parliament, re-affirmed the countrys established energy policy objectives. The energy policy decision contained measures designed to encourage more efficient energy consumption through the rationalisation of existing policy measures and the dissemination of knowledge at the national and regional levels. The decision also announced a new method to promote environmentally-friendly and renewable electricity production through a quota-based trading programme for green electricity certificates.
